AbstractUnspecific symptoms and rapid development of sepsis up to septic shock from systemic inflammatory response syndrome (SIRS) are well-known, important issues in neonatology. A common cause is the infection by Streptococcus agalactiae (Group B Streptococcus [GBS]) or Escherichia coli, which contributes significantly to neonatal morbidity and mortality. Whereas early-onset sepsis is normally derived from mother during birth, late-onset sepsis can be transmitted by the environment. Management of neonatal sepsis includes the maintenance of cardiovascular and pulmonary function besides antibiotic therapy. Due to the fact that until today, there are no reliable screening tests for detecting early sepsis, clinical assessment is considered to be of utmost importance.

Neonatal sepsis contributes significantly to neonatal morbidity and mortality. Group B streptococcus (GBS) is not a frequent cause of neonatal sepsis in India. Late onset sepsis by GBS presenting as focal infection like osteomyelitis is seen in only 3% of the total GBS sepsis profile in neonates. Here, we report a rare case of neonatal osteomyelitis with septic arthritis caused by GBS at an unusual site, the clavicle and sternoclavicular joint.

Introduction: Neonatal mortality in developing countries is usually due to an infectious cause.  The gold standard of investigation in developing countries is a positive blood culture.  It is important to know the aetiology of neonatal bloodstream infections so that empiric treatment can be effective.  Methodology: We conducted a retrospective clinical audit over ten years between January 2000 until December 2009, looking at the aetiology of both early and late onset neonatal sepsis.  We analysed data from 152 (23%) patient isolates out of 662 suspected cases of neonatal sepsis.  Results: Our study revealed that Gram-positive organisms were the predominant cause of both early and late onset sepsis; the common isolates were Staphylococcus epidermidis (34%) and Staphylococcus aureus (27%).  There were no isolates of group B Streptococcus.  Candida species was isolated only in patients with late onset sepsis (6.9%).  Bacterial isolates were relatively sensitive to the commonly used first- and second-line empiric antibiotics. Conclusion: Gram-positive organisms remain the major cause of neonatal bloodstream infections in our setup.  The findings of this study will guide clinicians in prescribing the right empiric therapy in cases of suspected neonatal sepsis before the definitive culture results are obtained.

We report a case of cellulitis of the soft tissue of the neck with group B streptococcus (GBS) sepsis in a 4-week-old baby boy presented with a 1-day history of fever, irritability and feed refusal. While in the hospital, a left-sided submandibular swelling extending to preauricular area started emerging, which progressed dramatically. Ultrasound scan of the neck confirmed inflammation of the underlying soft tissue while revealing multiple enlarged lymph nodes without any abscess formation and overlying soft tissue oedema. Blood cultures were flagged positive at 9 hours for GBS. The infant was treated with intravenous antibiotics for 2 weeks. GBS is considered a common cause of early-onset sepsis in neonates. However, it can also lead to late-onset sepsis in infancy with variable presentations. In our case, GBS sepsis manifested with cellulitis of the soft tissue of the neck along with swelling of local lymph nodes.

Group B Streptococcus is the most common pathogen found in neonatal sepsis in North America. OBJECTIVES: We describe 15 cases of neonatal infections by Group B Streptococcus (Streptococcus agalactiae) at a Neonatal Intensive Care Unit of a public and teaching hospital. METHODS: We conducted a study at Hospital de Clínicas de Porto Alegre, from January 1st, 1996 to June 30, 1999. Diagnosis of neonatal infection was established according to the findings of Group B Streptococcus in blood culture associated with alterations resembling sepsis on the basis of clinical picture and laboratory findings. RESULTS: Fifteen cases of neonatal infections by Group B Streptococcus were detected. Eleven cases consisted of early-onset sepsis, 2 cases of occult bacteremia and 2 cases of late-onset sepsis. Eight cases had septic shock (53%), 8 cases had pneumonia (53%), and 4 cases had meningitis (27%). Fourteen cases were diagnosed from a positive blood culture, and 1 case from evidence of these bacteria in pulmonary anatomopathological examination. Thirteen cases (87%) were diagnosed before 72 hours of life. We had 3 deaths (20%), and 3 cases of meningitis developing neurological deficits. CONCLUSIONS: Streptococcus Group B is one of the most important pathogens in the etiology of early-onset neonatal sepsis at our hospital, with high mortality and morbidity. However, we do not know the incidence of GBS neonatal infections at other hospitals. More data are needed to establish a basis for trials of different strategies to reduce these infections.

Introduction: India has the highest incidence of clinical sepsis i.e.17,000/ 1,00,000 live births. In Neonatal sepsis septicaemia, pneumonia, meningitis, osteomyelitis, arthritis and urinary tract infections can be included. Mortality in the neonatal period each year account for 41% (3.6 million) of all deaths in children under 5 years and most of these deaths occur in low income countries and about one million of these deaths are due to infectious causes including neonatal sepsis, meningitis, and pneumonia. In early onset neonatal sepsis (EOS) Clinical features are non-specific and are inefficient for identifying neonates with early-onset sepsis. Culture results take up to 48 hours and may give false-positive or low-yield results because of the antenatal antibiotic exposure. Reviews of risk factors has been used globally to guide the development of management guidelines for neonatal sepsis, and it is similarly recommended that such evidence be used to inform guideline development for management of neonatal sepsis. Material and Methods: This study was carried out using institution based cross section study . The total number neonates admitted in the hospital in given study period was 644, of which 234 were diagnosed for neonatal sepsis by the treating pediatrician based on the signs and symptoms during admission. The data was collected: Sociodemographic characteristics; maternal information; and neonatal information for neonatal sepsis like neonatal age on admission, sex, gestational age, birth weight, crying immediately at birth, and resuscitation at birth. Results: Out of 644 neonates admitted 234 (36.34%) were diagnosed for neonatal sepsis by the paediatrician based on the signs and symptoms during admission. Of the 234 neonates, 189 (80.77%) infants were in the age range of 0 to 7 days (Early onset sepsis) while 45 (19.23%) were aged between 8 and 28 days (Late onset sepsis). Male to female ratio in our study was 53.8% and 46% respectively. Out of total 126 male neonates 91(72.2%) were having early onset sepsis while 35 (27.8%) were late onset type. Out of total 108 female neonates 89(82.4%) were having early onset sepsis while 19 (17.6%) were late onset type. Maternal risk factors were identified in 103(57.2%) of early onset sepsis cases while in late onset sepsis cases were 11(20.4%). Foul smelling liquor in early onset sepsis and in late onset sepsis was 10(5.56%) and 2 (3.70%) respectively. In early onset sepsis cases maternal UTI, Meconium stained amniotic fluid, Multipara and Premature rupture of membrane was seen in 21(11.67%), 19 (10.56%), 20(11.11%) and 33 (18.33%) cases respectively. In late onset sepsis cases maternal UTI, Meconium stained amniotic fluid, Multipara and Premature rupture of membrane was seen in 2 (3.70%), 1(1.85%), 3 (5.56%) and 3 (5.56%) cases respectively. Conclusion: Maternal risk identification may help in the early identification and empirical antibiotic treatment in neonatal sepsis and thus mortality and morbidity can be reduced.

AbstractGroup B Streptococcus (GBS) is a major cause of neonatal morbidity and mortality. Serbia has not fully implemented preventive measures against GBS neonatal diseases. Therefore, we aimed to assess the maternal GBS colonisation and invasive neonatal disease rate, to reveal the trends of antimicrobial resistance and serotype distribution of GBS from various patient groups. Randomly selected non-invasive (n = 991) and all invasive GBS (n = 80) collected throughout Serbia from 2015 to 2020 were tested for antimicrobial susceptibility, capsular typing, and hvgA detection. Overall, 877/5621 (15.6%) pregnant women were colonised with GBS. Invasive GBS infections incidence in infants (0.18/1000 live births) showed a decreasing trend (0.3 to 0.1/1000 live births). Type III was overrepresented in infants with invasive infections (n = 35, 58.3%), whereas type V predominated among colonised adults (n = 224, 25.5%) and those with noninvasive (n = 37, 32.5%) and invasive infections (n = 8, 40%). The hypervirulent clone III/ST17 was highly associated with invasive infections (n = 28, 35%), particularly late-onset disease (n = 9, 47.4%), showing an increase from 12.3 to 14.8%. The GBS resistance to erythromycin and clindamycin was 26.7% and 22.1%, respectively, with an upward trend. The emergence of the hypervirulent clone III/ST17 and the escalation in GBS resistance highlight an urgent need for continuous monitoring of GBS infections.

Early onset sepsis due to group B streptococcus leads to neonatal morbidity, increased mortality, and long-term neurological deficencies. Interaction between septicemic GBS and confluent monolayers of human coronary artery endothelial cells (HCAECs) was analyzed by genome wide expression profiling. In total, 124 genes were differentially expressed (89 upregulated, 35 downregulated) based on a more than 3-fold difference to control HCAEC. Regulated genes are involved in apoptosis, hemostasis, oxidative stress response, infection, and inflammation. Regulation of selected genes and proteins identified in the gene array analysis was confirmed by Real-time RT-PCR assay (granulocyte chemotactic protein 2), ELISA (urokinase, cyclooxygenase 2, granulocyte chemotactic protein 1), and western blotting (Heme oxygenase1, BCL2 interacting protein) at various time points between 4 and 24 hours. These results indicate that GBS infection might influence signalling pathways leading to impaired function of the innate immune system and hemorrhagic and inflammatory complications during GBS sepsis.

Neonatal sepsis is a major cause of mortality and morbidity in newborn. The spectrum of bacteria which causes neonatal sepsis varies in different parts of the world. The organisms responsible for early onset and late onset sepsis are different. The objective of the study was undertaken to determine the pattern of bacterial isolates responsible for early and late onset neonatal sepsis. A prospective descriptive study over the period of one year was conducted at the Department of Neonatal Intensive care unit of Ad-din Women’s Medical College and Hospital, Dhaka, Bangladesh.Organisms were isolated from 8.7% of collected blood samples. The male female ratio of culture proven sepsis was 1.7:1. More than half (52.8%) of the evaluated neonates were preterm. & 56.3% had low birth weight. The gram positive and gram negative bacteria accounted for 24.1% and 75.9% of the isolates respectively. Around three fourth of the neonates (75.8%) presented with early onset sepsis, while 24.2% presented with late onset sepsis. Acinetobacter was the most common pathogen both in early onset (70%) and late onset (30%) sepsis. Pseudomonas (89.4%) was the second most common pathogen in early onset sepsis. Total mortality rate was 5.7%. Pre term, low birth weight and gram negative sepsis contributes majority of mortality.Gram negative organism especially Acinetobacter found to be commonest cause of sepsis. Pseudomonas was second most common but contributed highest in late onset sepsis and neonatal death due to sepsis.

Objective: To find out the bacterial pathogens in neonatal sepsis and todetermine antimicrobial sensitivity patterns of these pathogens. Place and Duration: At the Neonatal Unit of GhurkiTrust Teaching Hospital Lahore, from February 2003 to December 2004. Design: It was an analytical comparativestudy, done in prospective fashion. Subjects and Methods: A total of 100 culture proven neonates of sepsis wereincluded. Clinical data including neonatal and maternal history, physical examination and laboratory data includingblood counts and cultures were recorded. The cases that have already been given antibiotics were excluded. Standarddisc-diffusion method was used to assess the sensitivity pattern for the antibiotics (ampicillin, gentamicin, cefotaxime,ceftazidime, amikacin and imipenem). Results: Out of total of 100 cases, 64 belonged to Early onset Sepsis (EOS)and 36 belonged to Late onset Sepsis (LOS). Gram negative organisms were isolated from more than 80% of thecases. E. Coli was the commonest isolate (n=34), followed by Klebsiella (n=30) and Pseudomonas (n=13), involvingboth early and late onset groups. No isolate of group B streptococci (GBS) was found. Out of 34 isolates ofE.Coli,14.70%(n=5),17.6%(n=6),41.17%(n=14),61.76%(n=21),79.4%(n=27) and 97.05%(n=33) were sensitive toampicillin, gentamicin, cefotaxime, amikacin, ceftazidime and imipenem respectively. Klebsiella and Pseudomonas alsoshowed a low sensitivity to ampicillin, gentamicin, and cefotaxime, while good sensitivity to amikacin, ceftazidime andimipenem. The mortality was significantly high (P<0.05) in low birth weight infants. Conclusion: Improvement inantenatal and natal services is mandatory to reduce incidence of neonatal sepsis and related mortality. Most of theorganisms are resistant to commonly used drugs. Surveillance is required on regular basis.
